Struct SmartPointerDef

#[non_exhaustive]
#[repr(C)]
pub struct SmartPointerDef {
    pub vtable: &'static SmartPointerVTable,
    pub t: &'static Shape,
    pub flags: SmartPointerFlags,
    pub known: Option<KnownSmartPointer>,
}

Describes a smart pointer — including a vtable to query and alter its state, and the inner shape (the T in Option<T>).

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

vtable: &'static SmartPointerVTable

vtable for interacting with the smart pointer

t: &'static Shape

shape of the inner type of the smart pointer

flags: SmartPointerFlags

Flags representing various characteristics of the smart pointer

known: Option<KnownSmartPointer>

An optional field to identify the kind of smart pointer

Implementations

impl SmartPointerDef

pub const fn builder() -> SmartPointerDefBuilder

Creates a new SmartPointerDefBuilder with all fields set to None.

Trait Implementations

impl Clone for SmartPointerDef

fn clone(&self) -> SmartPointerDef

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SmartPointerDef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for SmartPointerDef

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SmartPointerDef

fn eq(&self, other: &SmartPointerDef) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
